Drakengard 1/2's dubs weren't excellent, but they were not even close to the bottom of the barrel of that era of dubs alone. Like most passable dubs, it had good actors (Angelus, Legna), and not so good actors (Manah). That's why there is a pretty big spectrum in terms of "good dubs" and "bad dubs." Even in this case, the "budget" part of budget localization can mean many things, but not necessarily indicative of overall quality. Deadly Premonition is "budget," but it isn't offensively terrible stuff.
I mean, Star Ocean 4 had a good ensemble in terms of actors and directors and probably wasn't all that budget on paper, but, well...
